Nanostructure array optoelectronic devices are disclosed. The optoelectronic device may have one or more intermediate electrical contacts that are physically and electrically connected to sidewalls of the array of nanostructures. The contacts may allow different photo-active regions of the optoelectronic device to be independently controlled. For example, one color light may be emitted or detected independently of another using the same group of one or more nanostructures. The optoelectronic device may be a pixilated device that may serve as an LED display or imaging sensor. The pixilated device may have an array of nanostructures with alternating rows and columns of sidewall electrical contacts at different layers. A pixel may be formed at the intersection of a row contact and a column contact. As one example, a single group of one or more nanostructures has a blue sub-pixel, a green sub-pixel, and a red sub-pixel.
